Review by: phil sellwoodEli
nicely presented kit with excellent plan. took 8 days to build and fit motor to F5 spec with Hacker A7 geared motor- plan shows conversion and 2 motor bulkheads are included with different hole spacings. went together very well though tailplane pylon is fiddly. wing tips are very weak and I braced them with bent wire at T.E. and carbon rod into mainspar. turned up some stainless ballast bars to give an extra 100g and have now flown with and without ballast- very impressive all-round. looking forward to some competitions.
Review by: Pete StartupEli F3-RES
Truly excellent kit, the laser cutting being the best I have seen. With an eliptical wing plan and tapered carbon fibre tube spars the laser cutting had to be spot on - and it was, everything fitted. All materials are top quality. Mine came out slightly heavy at 475 grams but I made no effort to keep the weight down as I wanted to use it more as a light wind slope soarer. I flew it today in a 'bit of a breeze' and as I suspected in the conditions, the performance was better with the ballast fitted. In very light air it will be fine without the ballast - it flies very well indeed. Spoilers are very effective too. I may even invest in a bungee!
Very highly recommended and of course top service from Neil.
Review by: Gary MEli - F3-RES kit
This is simply an outstanding kit and a complete joy to put together. The full size plan is a work of art and should be framed and hung up in the workshop. Quality of everything is superb and as long as you have a degree of building ability will not be a problem. Having said that, with more than fifty years now of making model airplanes, there were still a couple of mistakes made. One too embarrassing to mention. And if building another one, half a dozen things I would do differently. But on the whole, simply outstanding. Finished model looks lovely, slightly heavier than planned at 447 gm, and ready for maiden flight, hopefully soon. Build one, you will love the experience as I did. GM.
Review by: JonathanFIRST IMPRESSIONS OF KIT - EXTREMELY GOOD
Not a lot to report just yet (only just purchased and delivered the next day, thanks Neil!) but a close study today of the kit contents, the plan and instruction sheet, and the Google Album as well, reveals an extremely good quality product, which should go together without fuss.
Looking forward to building and eventually flying.

Kit arrived as other items before within three days. this is a really well made kit. I won't be starting on it just yet as other projects in hand. Thanks Hyperflight.
Review by: Bob GoodenoughAmazing Order Turnaround
Ordered late afternoon and delivered just over 24 hours later. I've looked longingly at the plan and the kit components but am not yet ready to start building. The quality of the balsa and the part-cutting is very impressive. The English translation of the build instructions is a little challenging but I think I've worked it all out. "Controll turning of the wing, on tip-1 negative 1-2mm ......" was particularly challenging but I'm assuming that it really does mean washout.
Hyperflight have a fabulous selection of kits and their response to customer orders is second-to-none. I know that obtaining balsa kits from Europe is very difficult at the moment and I hope that will be resolved because I look forward to building more of these.
HyperFlight comment: Yes it means washout.
